摘    要:目的 了解昆明某基地蔬菜中总α、总β放射性水平。方法 采集该蔬菜种植基地不同品种的蔬菜,用FYFS-400X型低本底α/β测量仪,测量样品中总α、总β放射性水平。结果 叶类蔬菜中总α放射性水平为(0.62 ±0.59) Bq/kg,范围为 (0.23~1.66) Bq/kg,总β放射性水平为 (106.3 ±27.6) Bq/kg,范围为 (68.4~125.3) Bq/kg;茎类蔬菜中总α放射性水平为 (0.45 ±0.26) Bq/kg,范围为 (0.30~0.64) Bq/kg,总β放射性水平为 (86.5 ±17.6) Bq/kg,范围为 (71.7~113.4) Bq/kg;根类蔬菜中总α放射性水平为 (0.32 ±0.19) Bq/kg,范围为 (0.28~0.39) Bq/kg,总β放射性水平为 (119.5 ±31.2) Bq/kg,范围为 (91.2~141.3) Bq/kg。结论 昆明某种植基地蔬菜中总放射性水平相对较低,属于正常本底水平。

Abstract:Objective to understand the radioactivity levels of the gross α and β in a vegetable base in Kunming. Method Different varieties of vegetables in the vegetable planting base were collected and the radioactivity levels of gross α and β in the samples were measured with FYFS-400X low background α/β measuring instruments. Results The gross α and β radioactivity and its' ranges were (0.62 ±0.59) Bq/kg (0.23~1.66) Bq/kg and (106.3 ±27.6) Bq/kg (68.4~125.3) Bq/kg in leafy vegetables, respectively. The gross α and β radioactivity and its' ranges were (0.45 ±0.26) Bq/kg (0.30~0.64) Bq/kg and (86.5 ±17.6) Bq/kg (71.7~113.4) Bq/kg in stem vegetables, respectively. And the gross α and β radioactivity and its' ranges were (0.32 ±0.19) Bq/kg (0.28~0.39) Bq/kg and (119.5 ±31.2) Bq/kg (91.2~141.3) Bq/kg in root vegetables, respectively. Conclusion The total radioactivity level of vegetables in a planting base in Kunming was relatively low and at the normal background level.
Keywords:Vegetables  Gross α Radioactivity  Gross β Radioactivity
